Abstract The Research with Adaptive Particle Imaging Detectors (RAPID) spectrometer for the Cluster mission is an advanced particle detector for the analysis of suprathermal plasma distributions in the energy range from 39-400 keV for electrons, 28-1500 keV (4000 keV) for hydrogen, and 10 keV/nuc - 1500 keV (4000 keV) for heavier ions.

Mission Description Cluster is the first constellation of four scientific spacecraft to study the Earth-Sun connection in three dimensions. Cluster offers unique opportunities to investigate physical processes in near-Earth space. Those processes are essential to study and understand the effects of the Sun on the vast Earth’s environment that is a highly varying system both in time and space. The four Cluster spacecraft in a polar orbit are unique in their ability to obtain a three-dimensional picture of medium and large-scale plasma structures. The varying Cluster spacecraft formation from 3 km to a few tens of thousands kilometres along the orbit enables multi-point local measurements of different regions at different scales that cannot be done with any other space mission.
